The following Java code example dynamally creates a DDX
document that disassembles a PDF document. A new PDF document is
created for each level 1 bookmark in the input PDF document. This
code example contains two user-defined methods:
createDDX: Creates an org.w3c.dom.Document object
that represents the DDX document that is sent to the Assembler service.
This user-defined method returns the org.w3c.dom.Document object.
convertDDX: Converts an org.w3c.dom.Document object
to a com.adobe.idp.Document object. This method
accepts an org.w3c.dom.Document object as an input
parameter and returns a com.adobe.idp.Document object.
Both
of these methods are invoked in this quick start. (See Dynamically Creating DDX Documents.)
/*
* This Java Quick Start uses the EJB mode and contains the following JAR files
* in the class path:
* 1. adobe-assembler-client.jar
* 2. adobe-livecycle-client.jar
* 3. adobe-usermanager-client.jar
* 4. adobe-utilities.jar
* 5. jbossall-client.jar (use a different JAR file if the LiveCycle Server is not deployed
* on JBoss)
* 6. jacorb.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss)
* 7. jnp-client.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss)
*
* The JBoss files must be kept in the jboss\client folder. You can copy the client folder to
* your local development environment and then include the 3 JBoss JAR files in your class path
*
* These JAR files are located in the following path:
* <install directory>/sdk/client-libs/common
*
* The adobe-utilities.jar file is located in the following path:
* <install directory>/sdk/client-libs/jboss
*
* The jbossall-client.jar file is located in the following path:
* <install directory>/jboss/client
*
* If you want to invoke a remote LiveCycle Server instance and there is a
* firewall between the client application and the server, then it is
* recommended that you use the SOAP mode. When using the SOAP mode,
* you have to include additional JAR files located in the following
* path
* <install directory>/sdk/client-libs/thirdparty
*
* For information about the SOAP
* mode and the additional JAR files that need to be included,
* see "Setting connection properties" in Programming
* with LiveCycle
*
* For complete details about the location of the LiveCycle JAR files,
* see "Including LiveCycle Java library files" in Programming
* with LiveCycle
*
* This quick start dynamically creates the following DDX document:
* <?xml version="1.0" encoding="UTF-8"?>
* <DDX xmlns="http://ns.adobe.com/DDX/1.0/">
* <PDFsFromBookmarks prefix="stmt">
* <PDF source="AssemblerResultPDF.pdf"/>
*</PDFsFromBookmarks>
* </DDX>
